CONTROL H nes.

Application f led March 9, 1927. Serial No. 173,878.

This invention relates to control hinges, and more particularly to adjusters for swinging easements, transoms: and the like, and it is an object of this invention to provide a device which may be attached .to the jamb adjacent the swinging casement and which is attachable to the'casement itself indicated which can be readily made of.

sheet-metal stampings and which at the same time is light and strong.

A still further object is to providea novel construction of control. hinge, whereby in the act of swinging the easement, a powerful 5 leverage is exerted on the same in the direction of the opening or'closing thereof, to readily startthe same from the jamb as the pressure exerted is applied thereto manually.

A still further object of this invention is to provide a devicewhich is strong and durable in construction, operates efiiciently and is well adapted to perform the services re quired of the same.

With these and many other objects in view, which will more readily appear as the nature of the invention-is better understood, the same consists in the novel construction, combination, and arrangement of parts, which will hereinafter he more fully described, illustrated and claimed.

The essential features of the invention involved in the carrying out of the objects indicated are susceptible to modification; but a preferred embodiment ofthe invention is shown in the accompanying drawings, in

which Figure 1 is a top plan view showing my device applied to the jamb of a swinging Like reference characters designate cor responding parts throughout the 'several' figures of the drawings, and in my invention,

while the ,various elements thereof may be constructed in any suitable manner and of any suitable material, yet it is preferable to form the hinge of sheet-metal stampingson account of the cheapness, lightness and strength of thelatter; but irrespective of these details in manufacturing, the essential features of the invention are alwayspreserved.

:The device involves in its general zation,:a hinge having leaves or sections '1 and 2. The sectionl being applied tothe jamb 3 of a casement in the manner-inch cated inFigure 1, and the section 2 being applied to the casement itself as shown in this same figure. The section 1 is preferably in the form of. a substantially Z-shaped stamping having aport-ion 4 attached to-the jamb, a central portion 5 through which thereis an aperture 6 and a portion 7, the outer end of which is curved to form a ournal for a pintle 8. The section2 of the hinge is preferably in the form of. a slightly bentmetal stampinghavinga portion 9 attached to the. easement and a portion 10, the

-- outer end of which is rounded in the manner -s1m1lar to which the portion 7.0f the section 1 is rounded, alsov to receive the pintle 8. Cut-out portions13 and 14 are formed in organ? each of the. hinge sections to provide a space wherein a pairof beveled gears may operate-and which'will be described at apoint later in'this specification. Second cut-out portions 15and 161a're formed on adjacent edges of each of the :hinge sectionsrespectively, so that the sectionsmay, be complementary and cooperate upon thepintle to form a hinge having perfect alignment with respect to the pintle 8. The various cut-out portions in the hinge are so arranged that each section may be reversed upon the other to permit opposite swinging of a casement if ,the same is necessary. Loosely mounted onthe pintle 8 which acts as a shaft therefor, is a beveled gear having a pair of. lugs 21 and 22, and a supporting shank 27. These'lugs 21 and 22 are spaced a slight distance apart and receive the upper edge of the cut-out portion 13 in the'section 1. Extending through the jamb 3 of the casement is a shaft 23 having on the outer end thereof a bearing 24. The outer end ofthis shaft is squared as at 25 to receive a square, apertured crank-handle 26. A coil-spring is disposed around this squared portion and a friction disc 29 abuts against the coils spring and the bearing 24 fora purpose to" The inner end of be described hereinafter. I the shaft 23 has thereon, a beveled gear 28 having teeth which engage the teeth of the beveled gear so that rotation of the gear 28 will cause rotation of the gear 20 and con sequently of the casement itself. From the foregoing it is thought that the construction of the herein described control hinge will be apparent without further description of the parts, and the operation of this device v will now be described.

The device is applied to the operative parts of the easement and amb as shown 1n Figure 1. \Vhen it is desired to openthe casement or, partially open the same, the

handle 26 is manually rotated and motion is imparted to the beveled gear 28 through the shaft, 23; This motion of the beveled gear 28 causes motion "of thebeveledgear 20, and

the lugs 21 carry the hinge in a rotary direction upon the pintle 8 so that the easement will be swung open. If the casement should be swung from its opposing edge in an opposing direction, it is merely necessary to remove the pintle 8, which may easily be done by removing one of the small knobs on the pintle, and the hinge may be reversed by virtue of its construction, and the beveled gear 2O may also be reversed. upon the pintle so that it' will occupy a position below the beveled gear 28. The device Will then be set so that it may be applied to a casement that For example, my device may readily be ap plied to swinging transoms by providing a. small pulley. in place of the handle 26, and

permitting a belt orthe like tofrun down the side of the jamb or within the jamb itself, and providing a'suit'able handle at a convenient'point on the jamb whereby motion may be imparted through the said belt to the pul lcy thus serving to operate the parts.

Having thus described the invention, what is claimed and-desired to be'secu'red by 'Letters Patents, is: I a p 1. A hinge for swinging easements and the like comprising a pair of pivoted hinge.

leaves, one of which is attachable to the casement and the other to the jamb thereof, said leaves being provided with adjacent cut out portions, a gear mounted for rotation within said cut'out port1on, sa1d gear hav ng lugs arranged to engage oppositesides of the case ment'leaf, a second gear meshingwith said 1 first mentioned'gear, and manually operated means for rotating said second gear to rotate sald first mentioned gear to cause the casement leaf to swing upon the jamb leaf.-

, 2. A hinge-for swinging easements and the like comprising a pair of hinged leaves, a pintle pivoting them together, one of said leaves beingsubstantially Z-shaped and attachable toperpendicular planes upon the jamb, the other section being slightly bent and attachable to the inner edge of the casement whereby the outer. ends of said leaves. may close upon each other, out out portions in said leaves on either side of said pintle, a gear mounted on said pintle and within said out out portions, said gear being provided with upstanding lugs adapted to engage opposite sides of'the casement leaf, second gear meshing with the first gear, ashaft fast 1 to said, second gear and passingthrough said 'jamb, manually operated means for rotating said shaft, and frictionalmea'ns retarding the rotation of saidlshaft.

In testimony whereof I havefis'i'gned my name to this specificatioin i v SAMUEL B. ZIMMER.
